IMPROVEMENT iii METHODS AND APPARATUS FOR FLARlilG GLASSWARE.

Specification forming part of Letters lat nt No. fil fifi fififi, (loft-d April 1879; application filed March l, 157:"

I?) all whom it may concrrn:

Be it known that I, OLIVER l. JACKSON, of Pitlslmrg, in tho county of Allegheny and Stntc of Pennsylvania, hnvc invented ncertain now and nsclnl lilcthod of and Apparatus for l lnring Glassware; and 1 do hereby dcclaro tho following to ho a full, clear, and exnot description of the invcntion, such as will cnnlolc others skilled in the art to which it portcins lo malzc and use. it, reference losing land to tin: accompanying d ro-win gs, which form port of this spccilicolion, 1:: which laigurc l a. plain vim, and Fig. 2 a side elevation, of lilf, apparatus. Fig. 3 is 3, ohm oi a modifimiion.

This invention relates to a method of flaring gin sswlu'o zipg'iorzztns thorclbr; and consists in oscillating; o suitably-slmpcd 6X- pzinding or flaring tool on n lixcd axis while the article is forced. against in; and in the construction and con'ihinotion of dcviccs for giving this required oscillation, substantially as licrcinafter fully dcscribcil and claimed.

Glassware is flared in various modes. The article is forced upon astationnry ping or former, which, entering tho month of the artiole, expands it to the required degree. The objection is made to this lllOile that it causes the plastic glass to buckle and thicken beyond the tool, thereby destroying its previous outline to some extent. Another Way is to force the article upon a revolving tool, or force 2.- stotionary tool in the article while the latter 18 made to revolve. The objcction is rnznle to this Way that the constant revolution drags the glass and gives the article a threaded and uneven appearance, thus destroying; its beauty and trnnslnccncy.

My object; is to avoid all those objections; and 50 that end my invention is as follows:

A designates the expanding-tool,being of the solid character and form shown, or of any shape found suitable to the grade of Work to be done. This forms tho end of a, shaft, B, which is stepped in the hearings (J on a suitable hose, D. On the other end of shaft B is lieycd a crank, r, and n pitinzin, j", connects it to a Wrist-pin on Wheel 9,,which is revolved by a, belt, 71, passing over a wheel, 1', which can be revolved by hand or power.

ltcvoloior: of wheel 2 causes Wheel 9 to rc- "olvc, carrying its wrisi-nin around. This re- .li'lIOCillQS tho pitinan f, and it, through the .lz'mli c. oscillates the shaft 18 and former A. inns tho l'omxer runs hack and forth over the some surfaces, smoothing down the glass perfectly, and preventing the undue dragging of the gloss and consequent, threading.

It is obvious that, instead of the former, the article itself may ho oscillated.

Various (lci'ices can bc used for giving the oscillatory movement. Fig. 3 exhibits another in plan. F is the former on shaft 122, having the sqnarc twisted portion n. G is nnnt, norcd out t lit the twist, and guided by lhc cross-howl o slidin on the parallel shears Fill; G is rcciprocatcd by the pitman s and crank 1, and, being prevented from revolving, forces the shaft m to oscillate slightly.

Otli r devices can be readily substituted for those shown to produce the oscillatory move ment of tho lornicr, or of the article under manipulation, as mechanical knowledge will snggost Various devices for the purpose.

I claim as my inventionl. The heroin described mode of flaring glassware, consisting in forcing the article upon a suitably-shaped flaring-to0l and oscillating the tool on a fixed axis, substantially as described.

2. A flaring-machine for glassware, comprising a suitably-shaped tool or former and means for giving the some an oscillatory mo tion, substantially as described.

3. The described flaring-machine, consisting of the following elements in combination: a llaringtool, a shaft axially fixed to the some and adapted to receive oscillatory motion, and means, suhstan ially as described, for giving it said motion.

In testimony that I claim the foregoing I have hereunto sot my hand this 3d day of March, 1879.

OLIVER I JACKSON.
